Question

Two users must encrypt and transmit large amounts of data between them. Which of the following should they use to encrypt and transmit the data?

Options

  • ASymmetric algorithm
  • BHash function
  • CDigital signature
  • DObfuscation

Explanation

When encrypting large volumes of data for transmission, symmetric encryption is the preferred method due to its computational efficiency compared to asymmetric alternatives.

Common mistakes.

  • B. Hash functions are one-way mathematical operations that produce a fixed-length digest and cannot be reversed or used to decrypt data, making them unsuitable for encrypting and transmitting data.
  • C. Digital signatures use asymmetric cryptography to verify the authenticity and integrity of data but do not encrypt the actual content of a message for confidentiality.
  • D. Obfuscation simply makes data harder to read or understand (e.g., encoding or renaming variables) but does not provide true cryptographic security or protect data during transmission.
